State Rarity Rank:S1

A State Rarity Rank of S1 means: This plant is endangered/critically imperiled in New York because of extreme rarity (typically 5 or fewer populations or very few remaining individuals) or is extremely vulnerable to extirpation from New York due to biological factors.

Global Rarity Rank:G5

A Global Rarity Rank of G5 means: This species is demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.

Did you know?
All of our existing populations were discovered in the 1990s while none of the 13 historical records have been rediscovered. The genus name is from the Latin, scutella, which means dish and refers to the appendage at the base of the flower while the species name means leaves without teeth (Fernald, 1970).

There are four existing populations but all of them consist of fewer than 100 plants each. There are 13 historical records but most of them have been searched or are located in areas that are highly developed and are considered extirpated.

Most of the historical records are extirpated or have little chance of being rediscovered and only four small populations remain in the state. If surveys fail to locate new populations this negative trend could continue.
